Method and device for scheduling of dataflow components Embodiments relate to a method for scheduling dataflow components (), executed by a scheduling device (), comprising repeating the following steps for successive increasing input message rates (1/&#x3b2;): &#x2014;applying (S) an ingress message flow (F) at an ingress message rate (1/&#x3b2;) to a distributed dataflow comprising at least one dataflow component () executed by respective processing devices (), &#x2014;determining (S) a total latency (&#x394;t) of at least one of dataflow component (), and &#x2014;determining (S) a serving rate (&#x3bc;) associated with said ingress message rate (1/&#x3b2;) for said at least one dataflow component (), in function of said ingress message rate (1/&#x3b2;) and said total latency (&#x394;t), until the scheduling device () is unable to determine a serving rate (&#x3bc;) associated with the ingress message rate (1/&#x3b2;), thereby determining a maximum serving rate for said at least one dataflow component ().

A technique is provided for echo cancellation. The technique includes marking respective source signals with a respective marker signal to identify respective starting time references of the respective source signals and to identify respective transmitters to transmit respectively obtained marked source signals, transmitting the respectively marked source signals by the respective transmitters to at least one aggregate node, summing the respective marked source signals received by the at least one aggregate node to create a multicast signal for provision, via a multicast node, to respective receivers associated to the respective transmitters, determining respective round trip power normalization and round trip delay values for modifying, in the respective receivers, the respective marked source signals, to obtain respective delayed and normalized respective marked source signals, and subtracting, at the respective receivers, the respective round trip delayed and normalized marked source signal from the multicast signal to obtain respective echo cancelled multicast signals in the respective receivers.

The present invention provides improved security in a virtual machine. By extending the capabilities of modern secure processors, privacy of computation is provided from both the owner of the equipment and other users executing on the processor, which is an advantageous feature for rentable, secure computers. In addition to the hardware extensions required to secure a virtualizable computer, an infrastructure for the deployment of such processors is also provided. Furthermore, a signaling flow to establish the various relationships between the owner, user and manufacturer of the equipment is disclosed.

A method for prioritized data transmission to a common transmission medium from a plurality of interface modules coupled to it, for interfacing at least one input bitstream with said common transmission medium, whereby access is arbitrated on the basis of a module priority of each interface module, is such that, for at least one interface module, the module priority is dependent on at least one connection parameter associated to packets of said at least one input bitstream. An arrangement for performing this method is described as well as several variant implementations of the method and the arrangement.

Method for prioritised data transmission and data transmission arrangement

An access control method to control access to a communication channel of a plurality of units coupled to it, each unit having a first and a second own priority assigned to it, includes a first step of comparing and withdrawing units, based on the first own priorities of said units, and for these units that have not withdrawn after the first step, this first step is repeated but using the second own priorities of these remaining units. A method to control access to a communication channel interconnecting a multitude of pluralities of units coupled to it, includes the mentioned steps for a single plurality for at least one plurality amongst said multitude.
